Cloudflare DNS Security (Overview)

Cloudflare DNS Security (Overview)

Cloudflare is a company that provides an online service to help protect websites from DDoS attacks, malware, and spam. Cloudflare’s DNS servers are faster than those of other providers because they cache the results of every request on the network, eliminating some of the time-consuming steps in resolving domain names. This article will provide you with an overview of how Cloudflare works and what it can do for your website.

What is Cloudflare DNS Security?

Cloudflare DNS Security is a service provided by Cloudflare that protects your website from DDoS attacks, malware, and spam. It also provides an overall faster experience for your visitors because Cloudflare’s servers cache the results of every request. This eliminates some of the time-consuming steps in resolving domain names, such as having to consult another server or look up a record from a database. 

How Does it Work?

Cloudflare DNS Security works by routing customers’ website traffic through its own network and caching frequently requested data. The company says that this service is free for most users but plans are available if you have a larger audience or more complex needs to customize how Cloudflare routes requests on your behalf. When requests come into Cloudflare’s servers, they can be answered much quicker than before because cached records have been stored locally instead of being looked up from another server.

What Are The Benefits of Using Cloudflare DNS Security?

There are several ways that Cloudflare can improve your website’s performance and security, such as:

Lowering Latency 

Cloudflare handles more requests per second than most hosting providers because it operates from multiple data centers around the world so you may notice faster load times for visitors to your site.

Increasing Speed 

In addition to speeding up access time by caching responses locally, Cloudflare also minimizes Internet congestion on its network with features like “Anycast” routing which delivers traffic within 20 milliseconds anywhere in the world.

Protecting Against DDoS Attacks 

Because all incoming web traffic is routed through Cloudflare servers before it reaches your website, Cloudflare can help mitigate DDoS attacks by scrubbing traffic that looks malicious before it is allowed to enter your network.

Keeping Out Spam 

Cloudflare takes an aggressive approach against spammers and malware distributors with built-in tools like the “Firewall” which blocks requests from IP addresses known for suspicious activity or the “Challenge” system which asks senders of email messages to solve a captcha test before continuing through Cloudflare’s servers.

Configuring Custom Security And Performance Settings 

Cloudflare provides a dashboard that allows you to adjust the behavior of your site’s service on an individual basis. You can set up rules for specific URLs or applications, configure how often Cloudflare refreshes cached data, and more.

Lowering Costs 

Costs can be lowered by reducing bandwidth consumption because only requested content is sent from origin servers instead of entire pages being re-downloaded at each request; this also reduces load times thanks to faster response time when caching locally.

Monitoring Statistics About Traffic Patterns 

By doing this you can easily know where requests are coming from geographically as well as which browsers, operating systems, and devices people use to access your website most often.

Integrating With Other Services Through Cloudflare’s “API” 

This can be used to configure how data is routed over the web on your behalf, track user behavior, and set up custom security rules for specific URLs or applications.

What Are The Disadvantages of Using Cloudflare DNS Security?

Network Restrictions 

Because all requests pass through Cloudflare servers first they may encounter network congestion more frequently than if requests were being sent directly from your website without passing through another server in between. 

This could result in slower load times depending on what time of day it is or where visitors are located geographically because latency will vary based on average response times across their entire network.

Limited Support 

Cloudflare provides a knowledge base for finding solutions to common issues but they don’t offer phone or email support for when you need help immediately instead of requiring that you post questions in their online community and hope someone else has had the same problem before and already knows the answer.

Privacy Concerns 

Cloudflare is a third-party that could potentially spy on your traffic and store sensitive data for their purposes. This is something that you should consider before using their services.

Who Uses Cloudflare DNS Security And Why Are They Important?

Cloudflare DNS security and performance services are used by a wide range of sites for different reasons. Some common uses include:

  1. Ecommerce stores to speed up load times which can increase conversions, lower cart abandonment rates, and improve SEO (search engine optimization) as well as provide other benefits such as lowering costs through reduced bandwidth consumption or protecting against DDoS attacks; those that see spikes in traffic during peak periods may also benefit from Cloudflare’s caching capabilities.
  2. Portfolio websites – designers who want visitors to their portfolio pages to access them quickly so they will be more likely to contact the designer with future projects could use these types of services. Others who operate small photography studios might use it too because site visitors will be less likely to leave and more likely to contact them for future projects.
  3. Web developers – top-tier web development firms may use Cloudflare security services as a way of marketing their ability to create fast, secure websites that rank well in search engine results.

Things To Consider When Using Cloudflare DNS Security 

  • Cloudflare DNS Security is a third-party service that you need to subscribe to use.
  • Requests from visitors could experience longer load times depending on how much traffic their network typically handles at any given time, where your site’s visitors are located geographically, and what other websites they have cached for performance purposes.
  • Cloudflare is a third-party service that could potentially monitor and store sensitive data for its purposes.
  • The security provided by Cloudflare DNS Security is dependent on how you configure it, if at all. Some features are only available through their paid subscription service so you should carefully consider what your site needs before subscribing.
  • Since Cloudflare offers paid subscriptions to their service you need to carefully consider what features your site needs.
  • You’ll also want to make sure that any custom security rules or other configurations are properly set up for the best possible performance and protection of your website.
  • It’s a good idea to monitor traffic statistics like where requests are coming from geographically as well as which browsers, operating systems, and devices people use because this information can help inform how you configure Cloudflare DNS Security settings.


Today where even the biggest of the big companies and websites get easily attacked, Cloudflare provides the ultimate security in this mayhem. Cloudflare is used to increase the security of websites and also used to boost the speed of the internet. About 25 million people use Cloudflare for their companies, home, and office networks.
